Abstract
The invention relates to a hydrodynamic torque converter having an impeller wheel, a turbine wheel and an oscillation damper which is accommodated in the converter housing, and a converter lockup clutch. Two damper stages are arranged here as a serial damper between the output hub of the torque converter and the converter lockup clutch, and a damper stage is arranged between the turbine wheel and the output hub. In order to improve the damping properties, a rotary oscillation absorber is additionally provided which is arranged between the dampers and is also connected to the turbine wheel in a rotationally fixed fashion.
Claims16
A hydrodynamic torque converter (1) with a turbine (7) driven by an impeller (6) as well as housing (3) in which a torsional vibration damper (16) with multiple of damper stages (14, 15), a torsional vibration absorber (17) and a lock-up clutch (13) are additionally installed, wherein a first damper stage (14) and a second damper stage (15) are disposed between the lock-up clutch (13) and an output hub (12), the second damper stage (15) is disposed between the turbine (7) and the output hub (12) and the torsional vibration absorber (17) is parallel to both damper stages (14, 15).
